Specification of Letters Patent.

To all whom it may concern live it known that I, Lane W. Robinson,

a citizen of the United States, and a resident of Aurora, in the county of IIane, Eitate of Illinois, have invented certain new and useful Improvements in Pumping Mechanism, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to pumping mecha nism and particularly to a new and improved arrangement of driving means for connecting a horizontal engine to the ver tically extending shaft of a deep well centrifugal or turbine pump, It is one of the objects of my invention to provide new and improved means for oiling the working parts of such a connectin means. It isanother object of my inventlon to provide new and improved means for cooling the gearing and bearings of the pump head. It is another object' of my IIIV'EIltiOIL to improve mechanisms of this type in sundry details hereinafter pointed out. The preferred means by whichI have accomplished my several objects are illustrated in the draw-' ings and are hereinafter specifically described. That which I believe to be new and desire to cover by this application is set forth in the 1 claims.

In the draw1ngs:-

l igure 1 is a central vertical "secti'orr through a pump head embodying the preferred form of my improvements;-

I ig. 2 is an enlarged detail, partly in section, illustrating a split collar-construction V forming a part of the connecting means between the ump shaft and the lowermost thrust bearing for-supporting the vertical gear Fig. 3 is a top view of one end of the base.

Fig. t is a transverse vertical section through a portion of the pump, being taken upon a plane at right angles to the plane'- upon which'the section of Fig. 1 is taken; and l Fig. 5 is aview illustrating a-modified form of construction, a portion of the pumphead sleeves and a portion of the horizontal shaft-of the machine being broken away.

Referring to Figs. 1 to 4t, in which corresponding parts are indicated by the same reference characters,--

16 indicates a base havingmounted upon one end an engine 11 of any suitable type end of a shaft protecting casing 18 which serves to protect the shaft 16 and its bear ings from the water'forced upward through the pump casing 13 and out through the discharge pipe 19. Inasmuch as the pumping mechanism operated by the shaft 16 is to be of any suitable type, it is believed to be unnecessar to illustrateit herein.

The sha 't 16 is rovolubly and adjustably supported upon the pump head 12 by means of an anti-friction bearing 20 supported by,

a housing 21 mounted upon the upper end of the pump head 12, the said bearing being interposed between the housing 21 and a cap 22 which is feathered upon the shaft and is held in adjusted vertical position thereon by means of a screw-thded nut23. h pin 24: is employed for holding the nut 23 against rotation as may be desired. The housing 21 provides a chamber 25 about the bearing20'closed at its upper end by a capplate 26. A pipe 27 leads downward from any'suitable supply of oil or other appropriate lubricant to the interior of the chamber 25 for lubricating both the anti-friction bearing 20 and another bearing 26 mounted in said housing. The bearing 28 is further lubricated by a supply of .oil fed thereto through a pipe 29 communicating through a duct 30 with the interior of said hearing. The shaft 16 is held against upward movement by means of an anti-friction bearing 31 interposed between the bottom of the housing 21 and a bevel gear 62 feathered upon the shaft, the gear 32 being adjustable longitudinally of the shaft b means of a nut 33 having screw-threade engagement with a two-part split collar"'34-35, the parts of which are mounted in a groove 36 as is best shown in Fig. 2. An'additional hearing 36 is provided for the shaft 16 below the gear 32, a striding-box 37 of any suit- Patented hey. i. 11..

mesh with 'the gear 32. An anti-friction bearing 47 is interposed between the gear 44 and thebearing 41, serving to take up the end thrust of the shaft 42 toward the left in Fig. 1.

The shaft 42 is connected by. means of a suitable flexible coupling 48 with a sleeve 49-which loosely surrounds a short section of shaft 50 which is fixedly connected with the shaft 51 of the engine 11. The sleeve 49 is connected with the shafts 50 and 51 through the medium of a friction clutch of any suitable type. In the construction shown thefriction clutch comprises a drum 52, a friction band 53 adapted to be tightenedabout said drum upon a suitable swinging movement of warm 54, and a grooved sleeve 55 by a movement of' which toward the left in'Fig. 1 the arm 54 is given a swinging movement for tightening the band upon the drum.

As is shown by an inspection of Figs. 1

I and 4, the pump head 12 is divided by a wall 56 into two chambers 57 and 58, the chamber 57 being in communication with the chamber formed by the sleeves 38 and 39, the outer ends of which are suitably joined together by a vertically-extending wall. The chamber 58 is closed at one side by a cap 59 which has mounted .in it a pipe 60 through which the chamber .58 is adapted to be kept full of oil or other suitable 1ubri'-- cant from any suitable source, serving thus to keep the bearings 31, 36 and 47 and the interme'shing gears 32 and 44 properly lubricated. The {chamber 57 is connected by means of a pipe 61 with the water discharge head 14 by means of'which a supply of cold water is fed to said chamber about the bearings 40 and 41 andabout the chamber 58 in which the gears 32 and 44 are mounted. A

pipe 62 at one side'of the pump connects the chamber 57 with a chamber 63 formed in the. lower endof the housing 21 about the chain-- ber 25 in which the bearing 20 is located.

The cold water from the chamber 57 is adapted to rise through said pipe 62 and to escape therefrom through a pipe 64. By

this-means the working parts of the pump head are all kept properly lubricated and cooledfor eficient operation. 7 In Fig. 5 which shows a modified form of construction, the shaft 42 is connected to a shaft 65 by means of a flexible coupling 66 of any suitable type. The shaft 65 is supported by suitable bearings 67-68 carried by standards 6970, respectively, mounted upon the base 10, being provided with a heavy fly-Wheel 71 fixedly mounted thereon. The shaft 65 is connected by means of a flexible coupling72 with a sleeve 49 which in turn is connected by any suitable friction clutch mechanism with any suitable source of power. As shown, the clutch mechanism just referred to comprises a clutch sleeve 55*and ordinary friction clutch members 7172, and the source of power referred to is, as shown, an engine, a portion of which is indicated by 73. It is to be understood, of

, course, that any other suitable clutch mechanism than that just referred to may be employed in lieu of the one shown. As all of the remaining parts of the mechanism are the same as inFig. 1, the same reference numerals are applied to such parts. By the use of the construction shown 1n Fig. 5 I am enabled to use a single cylinder internal combustion engine without undue danger of stripping the teeth from the ears.

By the use of a friction c utch for coupling-the engine to the pump shaft, I am enabled to apply the power gradually from the engine to the shaft soas to bring the pump gradually up to its full speed driving, being able thus to drive the pump with less power than would be required if it were necessary to start the pump intooperationbefore the engine had assumed its full speed operation.
